WAstrolabe Reef is near Motiti Island, 20 kilometres NE of Tauranga, off the Bay of Plenty coast in New Zealand. The reef, which breaks the water surface at low tide, is a renowned scuba diving spot that drops off to 37 metres (121 ft) in different parts. The reef was named by Jules Dumont d'Urville after his ship Astrolabe, when it nearly ran aground there on 16 February 1827.
WBeveridge Reef is a submerged atoll located in the Exclusive Economic Zone of Niue, approximately 130 miles from Niue and 600 miles from the Cook Islands. The reef is normally submerged, with a small part visible at low tide. It has been the cause of several fishing boats running aground.
WBligh Reef, sometimes known as Bligh Island Reef, is a reef off the coast of Bligh Island in Prince William Sound, Alaska. This was the location of the 1989 Exxon Valdez oil spill. After the incident, US Code 33 § 2733 mandated the operation of an automated navigation light to prevent future collisions with the reef. Despite these efforts the tug Pathfinder ran aground on Bligh Reef on Dec 24, 2009, rupturing its tanks and spilling diesel fuel. Bligh Reef is also where Alaska Steamship Company's Olympia ran aground in 1910.

Tern Island, with an area of 26.014 acres (10.527 ha), has a landing strip and permanent habitations for a small number of people. It is maintained as a field station in the Hawaiian Islands National Wildlife Refuge by the United States Fish and Wildlife Service. The French Frigate Shoals are about 487 nautical miles northwest of Honolulu.
WHaymet Rocks were reported by J.E. Haymet, master and owner of the cutter Will Watch, when on passage between Auckland and Rarotonga; in 1863 the cutter passed between two rocks and struck on the northern of the two, damaging her false keel. The rocks are said to extend over a space of about a quarter of a mile, to have been distinctly seen, and with apparently 7 or 8 feet water on them. Haymet gave their position as 27°11′S 160°13′W, which would place them about 135 miles west of the position assigned to Orne Bank.

WMaro Reef is a largely submerged coral atoll located in the Northwestern Hawaiian Islands. It was discovered in 1820 by Captain Joseph Allen of the ship Maro, after whose ship the reef was named. With a total area of 747 square miles (1,935 km2), it is the largest coral reef in the Northwestern Hawaiian Islands. It contains 37 species of stony coral. Unlike most atolls, the coral extends out from the center like spokes on a wheel. Located about 850 miles northwest of Honolulu, Hawaii, Maro Reef contains about 1 acre (4,000 m2) of dry land which itself can be submerged depending on the tides. Some scientists believe that it "may be on the verge of drowning" because the reefs are detached and are vulnerable to strong storm waves.
